The false water cobra is a large snake that lives in South America. It is named after true cobras because it flattens its neck to look bigger when threatened, but it is not a true cobra. It is mildly venomous, and its bites rarely cause serious harm to people.1

Hoe om dit te herken

Background colour is olive green or brown, with dark spots and bands over much of the body.1
Bands and colour grow darker towards the tail.1
Large eyes with round pupils. The tongue is black.1
Belly is yellow or brown with dark flecks, which form three dotted lines. Males tend to be yellow underneath and females brown.1
Hatchlings and juveniles are much darker and lack the dark eyes of adults.1

Word dikwels verwar met: Its pattern and colouring look somewhat like those of true water cobras (Boulengerina). The easiest difference to see is the hood: when threatened, the false water cobra stays horizontal, while a true cobra rears up.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

This snake has enlarged rear teeth that are not grooved, and they are linked to a gland that produces oral secretions with proteolytic activity, meaning they break down proteins. In the few serious cases, symptoms included severe swelling, bruising, numbness, itching and dizziness. Most bites cause only mild pain and minor swelling.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Many bites have been recorded, but only four cases of significant reaction in humans are reported for this species. It is considered mildly venomous.1

Wat doen dit as dit bang is?

When threatened, it flattens its neck like a cobra, and can flatten lower parts of its body too, to look larger and more intimidating.1

As dit byt

Was die byt, hou die persoon kalm en kry mediese hulp. Sommige spesies (soos die boomslang) kan ure later dodelik wees.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

Captive-bred individuals can become quite tame and trusting, and many show a high level of intelligence.1

Temperaments vary a lot: some individuals are docile, while others are defensive or even aggressive.1

Males are much smaller than females, a difference called sexual dimorphism.1

It is mainly active during the day, which gives it good daytime vision thanks to its large eyes.1

Mite-breker

Mite: It is a true cobra.

Waarheid: It is not a true cobra. It hoods in a similar way, but stays horizontal instead of rearing up.1
